Toro Proline 14 clutch removal

I've got an older (1994) Proline and haven't been able to find the secret to removing the clutch assembly. The manuals don't seem to cover it, so maybe it's so simple that I just can't see the nose on it's face!
Anybody know?
Thanks, J

What problem are you having, the bolt? Best to use an air impact to remove the bolt. At this point it should slide off, maybe with some help if its been on a while. Make sure to disconnect the connector first.

Now this is assuming it is an electric clutch on a walk-behind. Whats the model number?

Thanks for the reply. The model # is 30176. I should have mentioned that other than never having worked on one of these great old machines, the initial problem I'm having is keeping the engine shaft from turning when trying to remove the bolt at the bottom of the clutch assembly, which I assume (maybe wrongly) is what needs to be done to remove the clutch.
Can you advise?
